Whether dealing with historically intact or novel ecosystems — the 47 percent of Earth's ice - free land that has been altered by humans — scientists need to look at the paleobiology of the region, that is, what the ecosystem looked like before humans altered it, and seek to rebuild it to some degree toward that natural balance, Barnosky said.

Key to assessing the health of today's rapidly changing ecosystems is understanding their history, which can only be read from the fossil record, or the paleobiology of the region, the scientists argue.
